Metro put out an article with the racist headline "Sorry straight white men, Doctor Who was never made for you". Shockingly, this didn't go over well with the fans, and the backlash was so severe it appears Metro has ended up deleting their entire Twitter/X account in response. https://twitter.com/MetroUK
And the writer of that article protected her account.
There's been active efforts to track them down, and people have donated a lot of old episodes when they found them, but yeah, the current state is pretty bad.
Who knows, maybe we'll get lucky int he future, and some collector will have a shitton of the lost episodes, or not. either way, enjoy what we have, I suppose.
Sorry if I came off like a downer.
